Abstract

A device for allowing a crossbow to be released from a drawn position without damaging the crossbow. The device may comprise an elongated member having a substantially cylindrical shape that can be positioned on the upper surface of the barrel of a crossbow. The device may comprise a notched end shaped to receive the bowstring of the crossbow and allows the device to be projected by the bowstring upon actuation of the crossbow'"'"'s trigger lever.

Claims

1. A bolt comprising:

a tip portion,

comprising a first compression zone located at a first end of the tip portion; and

comprising a unitary structure fully defining a first collapsing aperture

said unitary structure adapted to absorb kinetic energy by undergoing deformation,

said deformation occurring in such a way that the deformation substantially plastically deforms both the unitary structure and the first collapsing aperture;

a notched portion comprising;

a nock, wherein the nock shaped to receive a bowstring;

a vane portion, wherein the vane portion at least partially increases the aerodynamic properties of the device; and

,

a scent capillary, wherein the scent capillary

causes a scent to be released upon the device being fired from a crossbow.

2. The bolt of claim 1, further comprising:

a directional marking comprising a writing or a symbol adapted to indicate the proper positioning of the bolt on the crossbow.

3. The bolt of claim 1, further comprising:

a multi-piece design comprising a coupling assembly, wherein the coupling assembly allows for the selective coupling of the tip portion and the notched portion to form an elongated member having a substantially cylindrical shape.

4. The bolt of claim 3, wherein the coupling assembly comprises:

a first coupling portion, wherein the first coupling portion is formed at a second end of the tip portion and comprises a reduced diameter portion that can be received by a recess formed in a first end of the notched portion;

a second coupling portion, wherein the second coupling portion selectively retains the first coupling portion within the recess.

5. The bolt of claim 1, wherein the tip portion further comprises:

a second nock shaped to receive the bowstring.

6. The bolt of claim 5, wherein the notched portion further comprises:

a second collapsing zone having at least a first collapsing aperture.

7. The bolt of claim 1, wherein the device comprises a reusable device comprising a biodegradable composition.

8. A bolt comprising:

a tip portion,

comprising a first compression zone located at a first end of the tip portion, and

comprising a unitary structure fully defining a first collapsing aperture

said unitary structure adapted to absorb kinetic energy by undergoing deformation,

said deformation occurring in such a way that the deformation substantially plastically deforms both the unitary structure and the first collapsing aperture;

a notched portion comprising,

a nock, wherein the nock shaped to receive a bowstring,

a vane portion, wherein the vane portion at least partially increases the aerodynamic properties of the device;

a scent capillary, wherein the scent capillary causes a scent to be released upon the device being fired from a crossbow; and

wherein the tip portion and the notched portion are integrally formed as a single piece design unitary member having an elongated, substantially cylindrical shape.

9. A bolt comprising:

a body portion;

a tip portion comprising,

a first outer shell, wherein the first outer shell defines a first interior recess;

a notched portion comprising,

a second outer shell, wherein the second outer shell defines a second interior recess,

a nock shaped to receive a bowstring, and

a vane portion, that at least partially increases the aerodynamic properties of the device,

wherein the tip portion and the notched portion can be selectively attached to the body portion to form an elongated member having a substantially cylindrical shape that can be used to un-cock a crossbow;

a first compression zone located at a first end of the tip portion, said first compression zone comprising a unitary structure defining a first collapsing aperture, said unitary structure adapted to absorb kinetic energy by undergoing plastic strain; and

a second compression zone located on the notched portion, said second compression zone comprising a unitary structure defining a second collapsing aperture, said unitary structure adapted to absorb kinetic energy by undergoing plastic strain.

10. The bolt of claim 9, further comprising:

a scent capillary, wherein the scent capillary causes the device to emit an odor designed to lure game animals or to mask an unnatural scent upon being fired from a crossbow.

11. The bolt of claim 10, wherein the scent capillary is positioned at least partially within the first interior recess.

12. The bolt of claim 10,

wherein either the first compression zone or the second compression zone is designed to undergo at least partial deformation upon a force being exerted on the bolt such that the partial deformation at least partially causes the scent capillary to emit the odor.

13. The bolt of claim 9, further comprising:

a biodegradable composition.

14. The bolt of claim 12, wherein said deformation that at least partially causes the scent capillary to emit the odor is plastic deformation.
